6% Inventor I af/f @M Patented Oct. 6, 1936 UNITED STATES PATENT OFFICE 13 Claims.

This invention relates to means for filtering the air inhaled by a person either through his nostrils or mouth, the general object of the invention being to provide a pair of these devices, one for the nostrils and the other for the mouth and each carrying filtering material, with a cord preferably of elastic material connecting the devices together in an adjustable manner, the cord having portions passing over the ears of the user for holding both devices in place.

Another object of the invention is to so construct and arrange the parts of the nose device as to make it adjustable for use with diierent size noses and for any required size of filtering material.

This invention is an improvement over that forming the subject matter of my Patent No. 1,802,275, dated April 21, 1931 and forms a continuation in part of my applications Serial No. 376,700 filed July 8, 1929 and Serial No. 656,339, led February 11, 1933.

This invention also consists in certain other features of construction and in the combination and arrangement of several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:-

Figure 1 is a perspective view of the invention.

Figure 2 is a vertical sectional view with parts in section of the nose device, this View showing how the device engages the lower part of the nose.

Figure 3 is a view of the gauze casing or pocket which is provided with a ap or extension.

Figure 4 is a view of the arcuate member with the channels at its ends for connecting two sections of a frame together.

Figure 5 is a perspective View showing the parts of the nose device separated.

Figure 6 is a section on the line 6--6 of Figure 2, showing how the extension of the sleeve engages a part of a rod.

Figure 7 is a view of the frame of the mouth device.

Figure 8 is a sectional detail view showing how the gauze casing or pocket encloses a frame and a pointed member of the frame passes through a part of the casing.

Figure 9 is a detail view showing how a sleeve (Cl. 12S-146) and having their lower extremities rolled to form l0r the sleeves 2. At the point of junction of the downwardly extending portions with the extremities of the limbs, loops 3 are formed for engaging the partition of the nose as shown in Figure 2 with the sleeve carrying parts located below l5` the nose and these parts facilitate the placing of the member in engagement with the partition and its removal therefrom and by making the strip of resilient material, it can be bent to adjust it to different sizes of nose partition members and 20 the adjustments can be made by manipulating the reduced lower portion of the U-shaped member I so as to widen or decrease the space between the loops 3.

The device also includes a pair of rods 4 each 25 of which has its lower end bent as at 5 to provide a substantially right angular part and then this part is bent again as at 6 and nally the terminal of the rod is bent upwardly to provide the vertical part l which ts in a sleeve 2 and is frictionally 30 held in place by an extension 2' depending from the sleeve and slightly bent to engage the part 1 as shown in Figures 6 and 9. Thus each part 1 is frictionally held in its sleeve but the rod can be partly turned so as to move the two rods to- 35 ward or away from each other.

An arm 8 has a sleeve 9 formed on one end thereof for slidingly but frictionally engaging each rod 4 and the free end of each arm is slightly tapered as shown in Figure 5.

The device also includes a pair of frames, each of which is composed of a pair of substanti-ally L-shaped sections I0 and an arcuate member I I which has channels I2 at its ends, one of which receives one limb of one member I0 45 and the other a limb of the other member'ID as shown in Figure 5. The opposite limbs of the two members I0 are free of each other and the outermost one of these limbs is bent into hook-shape as shown at I3. One of the channels 50 I2 is adapted to receive an arm 8 so as to support the frame from a rod 4 and all of these parts are preferably of resilient material so that after the parts are adjusted they will be held in adjusted position by friction.

As will be seen the frame composed of the parts I can be adjusted both lengthwise and to width and the frame can be adjusted on the arm 8 and the arm 8 can be slid as well as rotated on the rod 4 while the rod can be partly rotated in relation to the nose-engaging member due to the fact that its upturned end 'I can be partly rotated in the sleeve and all of the parts are frictionally hel-d in adjusted position.

A casing or pocket I4 receives each frame and one of the casings or pockets is formed with a flap or extension I5 for covering the front space between the two frames and the front lower portion of the nose, when the frames are in operative position as shown in Figure 1. Of course, each casing is provided with an openingA in one edge for permitting the frame to be inserted and removed and pointed members I6 are carried by certain parts of the frame penetrating the casing to hold the same in place. I prefer to place these pointed members one in one of the members I0 at the corner thereof and the other in the central portion of the arcuate member II as shown, though they m-ay be placed wherever desired or necessary.

From the foregoing, it will be seen that the various parts of the device can be readily adjusted to facilitate it being placed in position and. its removal and to t or conform to noses of various sizes and shaped and that the frames can be readily adjusted for accommodating any required size of filtering material or casings. These casings may be formed of any suitable material such as very fine gauze and by having the hooks I3 formed on the outermost limbs there is no danger of these ends puncturing the material.

The mouth covering member B is composed of a frame I'I of slightly resilient material covered with a filtering material I8.

In order to hold the two devices in position with the device A protecting the nostrils and the device B the mouth, I provide a cord I9 preferably of elastic material which has its intermediate part looped and tied around the lower portions 5 of the rods 4 as shown at 2|! with portions of the cord passing through the filtering material as shown vat 2l after which the cord forms two loops for passing around the ears of the wearer with hooks 22 carried by the ends of the cord for engaging the endsvof the mouth member B as shown in Figure 1. Each hook has a resilient sleeve 23 formed thereon for frictionally receiving the cord so that the length of the loops can be adjusted to suit the wearer.

Thus it will be seen that the elastic cord holds the two devices in place While the U-shaped member I with its parts 3 helps to hold the nostrils protecting device A in place and also to steady the device.

As shown in Figures l and 2, the device when in use forms a substantially V-shaped protector covering the lower end of the nose and having portions resting against the upper lip so that air inhaled through the nostrils is filtered while air inhaled through the mouth is filtered by the device B.

As before stated, the device can be adjusted to fit different sizes and shapes of noses and the frames can be moved apart to facilitate putting the device in position or removing it from position.

, The invention may be used by travelers traveling by automobile, train or the like or by persons working in dusty places and workmen whose occupation requires that the air inhaled by them be filtered to protect their health.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims. l
